BullFrog rust blocker shields, cups and strips stop rust corrosion in enclosed spaces. They contain metal seeking VpCI's that will migrate throughout the space to form an invisible "molecular umbrella" of electrochemical inhibitors that seal metals against the air and moisture that cause rust and corrosion. They are environmentally safe, no nitrates, silicones, phosphates, heavy metals or harmful chemicals. Will not harm plastics, elastomers or painted surfaces and have no affect on electrical, mechanical or chemical performance. Each emitter protects an enclosure for a full year.
